Using graphite, moly, copper or aluminum, depending on the type of burn required, the machine becomes a high energy, low voltage, thermal shock producing source. The electrode in the machine vibrates up and down 3,600 times a minute. Each time the electrode touches the piece to be burned, an arc is struck. The arc has a point of contact temperature of approximately 5,300 degrees Fahrenheit. A constant supply of fresh water is pumped down through the electrode causing the molten metal to thermally break down, at the same time flushing the thermally shocked metal back out the discharge hole. The discharged pieces are normally less than 10 microns in size (less than a grain of sand). The water also acts as a heat exchanger, i.e. the only portion to get hot is the small area that the tip of the electrode contacts, unlike drilling where heat from the bit transfers to the matted portion. The "MDM" maintains everything at ambient temperature, except what needs to be removed.

INTEGRA can remove any size, or burn any configuration, from 40 thousandths of an inch to three inches in diameter in one pass. Larger studs or holes can be made using multiple passes. On average, the "MDM" is about 40% faster than conventional drilling, and even glazed or hardened studs or bolts are removed with no problem with the "MDM".
